Hereinafter, each configuration will be described with reference to the accompanying drawings.

Excellence

Rainwater pipe 40 is a conduit for rainwater to flow into the storage tank of the present invention, in Figure 1 and Figure 2a is a structure that can be directly connected to the external conduit for river discharge in Figures 1 and 2a, Figure 4a to FIG. As shown in 4c, the rain pipe 40 may be formed to have a length shorter than that of the first low concentration storage tank 20. Rain pipe 40 is installed on the ground or ground corresponding to the buried position of the rain pipe or sewage pipe, it is preferable to install the screen 41 in front of the initial excellent inlet 50 to be described later in order to filter large contaminants. In addition, as in the prior art, the screen 41 is preferably manufactured in a mesh form having a plurality of holes. At the rear end of the screen 41, an initial excellent inlet 43 is provided, which penetrates through the initial excellent inflow unit 50 to be described later and serves as an inlet for the initial excellent. The initial excellent inlet 43 is opened and closed by the operation of the opening and closing unit 60 to be described later. The operation of the opening and closing unit 60 will be described later.

In addition, in the accompanying drawings of the present invention, the rain pipe 40 is directly attached to the high concentration storage tank 10, the first and second low concentration storage tanks 20, 30, but may be installed at a higher interval.

Initial excellent inflow department

In order to separate and store only the initial rainwater flowing into the rainwater pipe 40, the initial rainwater flows into the high concentration storage tank 10. The present invention first enters the rainwater rainwater pipe 40 into the high concentration storage tank 10 first. An initial excellent inflow portion 50 is provided at the front end of the high concentration storage tank 10 so as to be supplied. The initial excellent inflow unit 50 may communicate with the initial excellent inlet 43 such as a general pipe or tube form so long as the initial excellent inlet flows into the high concentration storage tank 10.

1 and 2a shows an example in which the initial excellent inflow portion 50 is manufactured in the form of a tube in the high concentration storage tank 10. Initial excellent inlet 50 is installed outside the high concentration storage tank 10, the initial excellent inlet 50 may be produced in a form connected to the high concentration storage tank (10). Since the initial excellent inlet 43 at the rear end of the screen 41 of the superior pipe 40 is connected to the upper part of the initial excellent inlet 50, the initial excellent inlet 43 and the initial excellent inlet 50 are Maintain the corresponding position. Therefore, the initial excellent inflow unit 50 communicates with the initial excellent inlet opening 43 of the rain pipe 40 described above, and the initial excellent water flowing from the rain pipe 40 into the initial excellent inflow unit 50 flows in.

In the following drawings and description of the present invention will be described in the case where there is an initial excellent inlet 50, the initial excellent inlet 43 of the rain pipe 40 without a separate initial excellent inlet 50 is a high concentration Directly installed on the upper portion of the storage tank 10, the initial excellent water may flow directly into the high concentration storage tank 10. That is, in the present invention, although the initial excellent inflow unit 50 is preferably installed, it is not an essential configuration.

High concentration storage tank

The high concentration storage tank 10 is directly connected to the above-described initial excellent inflow portion 50, the rainwater entering the initial excellent inflow portion 50 is introduced into the high concentration storage tank 10. In the present invention, the high concentration does not mean an excellent value over a certain quantitative pollution concentration, and in the case of the initial excellent rain that begins to rain and flows by dissolving a large amount of contaminated materials such as soil, roads, buildings, etc., compared to the excellent after the initial excellent rain. It is called high concentration because it contains pollutants at relatively high concentration.

The high concentration storage tank 10, as in the conventional storage tank, as shown in the perspective view of Figure 1 is preferably a rectangular, it is possible to all the various types of storage tank that can store the rain, such as round. The high concentration storage tank 10 is divided into a first low concentration storage tank and a second low concentration storage tank, which will be described later, and a partition wall, and the partition walls are not open to each other so that rainwater may not communicate with each other.

2A illustrates a case where rainwater is introduced into the high concentration storage tank 10 through the initial excellent inflow portion 50 in a state where the opening and closing unit 60 to be described later is introduced so that the initial excellent water flows into the high concentration storage tank 10. However, when all of the high concentration storage tank 10 is filled, the opening and closing unit 60 automatically operates so that rainwater does not flow into the high concentration storage tank 10 anymore, so that the initial excellent inlet 43 is completely closed, thereby making the rainwater first. It should be flowed into the secondary and secondary low concentration reservoirs 20 and 30. Here, the meaning of "low concentration" means that the above-mentioned "high concentration" is mainly stored in the initial superiority, whereas the initial excellent storage tank 10 is filled after all the excellent storage is relatively excellent because of the relatively low pollution degree, it is expressed as low concentration, specific Pollution degree is not an expression.

Including the high concentration storage tank 10 described above in the present invention, the first low concentration storage tank 20 and the second low concentration storage tank 30 to be described later can be manufactured from a variety of materials, in particular, FRP (fiber-reinforced plastic) It can also be manufactured from synthetic resin materials such as).

draw

2B is different from FIG. 2A, the opening and closing unit 60 operates to block the initial excellent inlet 43, and the rainwater flowing into the rain pipe 40 does not flow into the initial excellent inlet 50, but the initial excellent inlet 43 is not shown. After passing through the first low concentration storage tank 20 (and the second low concentration storage tank 30) to fill the first low concentration storage tank 20 and the second low concentration storage tank (30).

The through-hole 42 of the rain pipe 40 is only in the upper portion of the first low concentration storage tank 20, and after the rain drops fall only to the first low concentration storage tank 20 to fill it, the first low concentration storage tank 20 and the first It is also possible to fill the second low concentration storage tank 30 beyond the partition W between the second low concentration storage tank 30.

2A and 2B, the opening and closing unit 60 is driven to open and close the initial excellent inlet 43. The opening and closing part 60 is a mechanical or electronic signal according to the level of the high concentration reservoir 10 by a buoy or a water level sensor (hereinafter referred to as "buoy" or "water level sensor""buoy" and denoted by reference numeral 61). To open and close by, but the technology for operating the configuration to act as a door to detect the water level is a known technique, since the implementation method is various, the present invention detects the water level through the opening and closing unit 60 through the initial excellent inlet It is not limited to the specific technique which opens and closes 43. In addition, although the opening and closing portion may operate electronically, in the present invention, it is preferable to operate mechanically. In the case of a mechanical device, the device is inexpensive and relatively less of a trouble.

As described above, the technology for sensing and opening and closing the water level is very diverse, but the two types will be described with reference to FIGS. 3A and 3B.

First, in Figure 3a, the buoy 61 for detecting the water level is connected to the elastic rotation wheel 63 by a wire of metal or synthetic resin material, the elastic rotation wheel 63 is a sliding door 62 which can move left and right. ) The elastic rotation wheel 63 is a wheel to which the elastic force to rotate in the counterclockwise direction (based on Figure 3a) by a spring or elastic material, etc., to rotate counterclockwise by the gravity of the buoy 61 connected to the wire The sliding door 62 is open to correspond to a state where the force and the force to rotate clockwise by the buoy are balanced.

Therefore, when the buoy is at the bottom of the high concentration storage tank 10 (before the initial rainwater enters the high concentration storage tank 10), the length of the wire is maximized, and the elastic rotation wheel 63 rotates clockwise as much as possible. Thus, the sliding door 62 moves to the right, so that the initial door opening 43 does not block the sliding door 62 at all, and the initial excellent inlet flows through the opening of the initial excellent opening 43 where the initial excellent opening is opened. Passed through the portion 50 is to be stored in the high concentration storage tank (10).

On the contrary, when the high concentration storage tank 10 is filled with the initial excellent water and the buoy 61 rises, the wire becomes shorter, and the elastic rotation wheel 63 rotates counterclockwise by the shorter wire length. When the sliding door 62 moves to the left side, and thus the sliding door 62 completely blocks the initial excellent inlet 43, the rainwater flowing into the rain pipe 40 flows to the through hole 43, and then through the hole. Through the first low concentration storage tank (and the second low concentration storage tank) is filled. That is, the degree of opening and closing of the sliding door 62 changes as the height of the buoy 61 changes. In addition, by adjusting the rotational force (tension) of the elastic rotary wheel 63, the sliding door 62 once opened until the buoy 61 rises to a certain degree or more remains open, and the buoy 61 remains. It is preferable to allow the sliding door 62 to close when it rises above a certain height.

3B illustrates a method of opening and closing using a blade, not a sliding door 62, in which a wire is connected to an elastic rotation shaft 65 through a rotation shaft 64 from a buoy 61. Similar to the above-mentioned elastic rotating wheel 63, the elastic rotating shaft, a force acting to rotate in one direction by a spring or an elastic material, the blade 66 is attached to the elastic rotating shaft (65). The elastic rotation shaft 65 is preferably designed to rotate in both directions between 90 ° in the design.

In the case of FIG. 3B, as in FIG. 3A, when there is no rainwater in the high concentration storage tank 10, since the buoy is at the bottom, the wire becomes long, and the elastic rotation shaft 65 turns to the right. The blade fixed to 65 also stands vertically, and the initial excellent inlet 43 is opened. On the contrary, when the high concentration storage tank 10 is filled, the buoys rise to shorten the length of the wire, so that the elastic rotation shaft 65 rotates to the left so that the blade 66 is horizontal to block the initial excellent inlet 43. Rainwater no longer flows to the high concentration storage tank 10, and flows further through the rain pipe 40 to flow from the through hole 43 to the first low concentration storage tank (and the second low concentration storage tank).

As described above, the technique of sensing the water level mechanically or electronically to operate and open the door and the similar configuration is so diverse that the present invention is not limited to the specific opening and closing method. In the present invention, it is preferable that the opening and closing part 60 is operated by mechanical means to open and close the initial excellent inlet 43. This is because the mechanical frequency of the failure is low, and the manufacturing cost is low.

The first Low concentration storage tank  And second low concentrations Reservoir

By the operation of the opening and closing unit 60 by the movement of the buoy 61 as described above, the first low concentration reservoir and the second low concentration reservoir as shown in Figure 2b is filled after the high concentration storage tank 10 is filled. . As shown in FIG. 2B, the rainwater may be stored at a low concentration relative to the first low concentration storage tank and the second low concentration storage tank by the opening of the rain pipe 40, and the rain pipe 40 may have a high concentration storage tank as shown in FIGS. 4A and 4B. It may be formed to extend only to the first storage tank 20 past the (10). 4A is an example in which the rain pipe 40 is slightly lower than the initial excellent inlet 43 after being installed as "L", and in the case of FIG. 4B, the height of the rain pipe 40 is constant.

The first low concentration storage tank 20 and the second low concentration storage tank 30 may both have a general rectangular shape, a circular shape, and the like, and preferably have a rectangular shape. The first low concentration storage tank 20 and the second low concentration storage tank 30 may be filled at the same time as described above, the first low concentration storage tank 20 is all filled first, and then the first low concentration storage tank 20 and The second low concentration storage tank 30 may be filled in the second low concentration storage tank 30 (W, may be provided with a through hole for a separate storm movement).

In the case of the above-described high concentration storage tank 10, the first low concentration storage tank 20, and the second low concentration storage tank 30, drain pipes 11, 21, and 31 are installed, respectively, and drain pumps 12, 22, and 32, respectively. By the end of storage, it discharges to the outside at a suitable time (for example, the time when rain stopped). The method of releasing rainwater from each storage tank to the outside using a drain pipe and a pump may be discharged to the outside by connecting the drain pipe to the bottom of each storage tank, or may be discharged to the outside by connecting the drain pipe to the top of each storage tank. For example, in the case of the perspective view of FIG. 1, the high concentration storage tank 10 displays all of the discharges to the outside through the drain pipe 11 and the drain pump 12 at the top and the bottom thereof. do. In FIG. 2A and the following drawings, the rainwater stored in the high concentration storage tank 10 through the lower portion and the first and second low concentration storage tanks 20 and 30 through the upper portion are discharged to the outside. .

In addition, the high concentration storage tank 10 and the washing water supply pipe 23 are connected to the middle height of the first low concentration storage tank 20 in an oblique direction, and one end of both ends of the washing water supply pipe 23 is provided with a valve. When the high concentration storage tank 10 is required to be washed, the valve is opened to send the excellent low concentration storage tank 20 to the high concentration storage tank 10 through the washing water supply pipe 23. This washing method will be described in more detail below.

External discharge method of stored rainwater

As described above, in the case of rainwater stored in the high concentration storage tank 10, the degree of contamination is relatively high, so it should not be immediately discharged to the stream and should be sent to an external sewage treatment plant. The drain pipe 11 is connected to the sewage pipe 13 connected to the sewage treatment plant to discharge the rainwater stored in the high concentration storage tank 10 to the sewage treatment plant.

On the other hand, the rainwater stored in the first low concentration storage tank 20 and the second low concentration storage tank 30 has a relatively low pollution degree, and is immediately discharged to the stream.

High concentration storage tank  Washing method

Unlike the high concentration storage tank 10 in the present invention, in the case of the low concentration algae tank divided into the first low concentration storage tank 20 and the second low concentration storage tank 30, all the rainwater stored in the second low concentration storage tank 30 to the river Unlike the discharge, the first low concentration storage tank 20 is separately installed to supply a supplementary rainwater for removing sludge of the high concentration storage tank 10 to the high concentration storage tank 10.

Referring to FIG. 5, when all of the initial rainwater is filled in the high concentration storage tank 10, it is sent to an external sewage treatment plant through the drain pipe 11. However, after draining the initial excellent water in the high concentration storage tank to some extent, the rainwater stored in the high concentration storage tank 10 has many sludge-type contaminants such as residues, and further remains through the drain pump 12. It is difficult to drain contaminants in the form of sludge. In this case, by opening the valve 24 of the first low concentration storage tank 20 and sending a relatively clean, free floating material, etc. to the high concentration storage tank 10 through the washing water supply pipe 23 (first low concentration) The water level of the storage tank 20 is lowered, h> h '), the water level of the high concentration storage tank 10 is increased (l <l'), that is, the amount of rainwater is increased again, so that the concentration of sludge is relatively low. By the drain pump 12, it is easy to drain from the high concentration storage tank 10 to the outside.

High concentration storage tank Sludge  How to remove

The storage tank of the present invention is the side of the high concentration tank 10, preferably far from the initial excellent inlet 50, in order to effectively remove the sludge (denoted by "s" in the figure) in the lower portion of the high concentration tank 10 It is preferable to have a separate sludge collection well 70 on the outer side of the high concentration storage tank 10.

6A and 6B illustrate an embodiment of a storage tank having a sludge collecting well 70 according to the present invention. As shown in FIG. 6A, an inclined path 15 inclined downward between the initial excellent inflow portion 50 and the high concentration storage tank 10. You can have more). As shown in Figure 6b, it is preferable that the ramp 15 is lowered toward the rear with respect to Figure 6a. The initial excellent inflow portion 50 and the initial excellent water flowing along the ramp 15 contains a high concentration of sludge (s), as shown in Figures 6a and 6b in the case of the ramp 15 by the ramp 15 by gravity In particular, since most of the sludge collects in the sludge discharge port 90 described later, as shown in FIG. 6B, it is easy to discharge the sludge into the sludge collecting well 70 later.

As shown in FIG. 6B, among the two sides of the high concentration storage tank 10, a sludge discharge port 90 is opened at a lower side of the initial excellent inflow portion 50 and a side thereof, and the sludge discharge port 90 is described above. Similarly to the buoy 61 and the elastic rotary wheel 63 used in, the elastic rotary wheel 92 is operated in accordance with the change of the height of the buoy 93, the sliding by the rotation of the elastic rotary wheel 92 The sliding door 91 may be operated to open and close the sludge discharge port 90.

Outside the sludge discharge port 90, the sludge collection tank 70, which can be formed in various shapes such as a square and a triangle, is positioned at a lower position than the sludge discharge port 90. Inside the sludge collection well 70 has a basket 71 formed with holes in the bottom and / or side in order to drain the water from the sludge to the drain 72. The basket 71 is lifted upward by manual or motor force and discharged manually or automatically to the outside.

7A and 7B illustrate a method of transporting and removing sludge to the outside by collecting the sludge after collecting the sludge into the sludge collecting well 70 through the sludge outlet 90.

In order to remove the initial excellent water stored in the high concentration storage tank 10, as described above, the initial excellent water is discharged to the sewage treatment plant using the drainage pump 12 to the drain pipe 11. In this case, the height of the buoy 93 is lowered, and when the elastic rotary shaft 93 rotates to operate the sliding door 91 to move upward, the sludge discharge port 90 is opened to the lower portion of the ramp 15. The sludge collected by gravity is discharged together with water to the sludge outlet 90 to be collected into the sludge sump 70, more precisely into the basket 71 in the sludge sump 70, as shown in Figure 7b, After the basket 71 is moved upward by the force of the motor or the manpower of the operator, the sludge is discharged to the outside by appropriate means.

bracket Reservoir  How to clean
